Passing Pixmaps between MainWindow and Dialog

[ramstormrage]

Hello again, Thanks for replying..
Ok I'll try that..

Anyways, my previous hunch was right, the QImage image object gets destroyed after the MainWindow:pen() function. In the showBrightnessDialog(), I tried to put another
QImage image(fileName); and it proceeded and displayed the pixmap inside the label as planned.

Just to need know why? Any ideas?

If the image object was going out of scope, you wouldn't be able to compile the application. It's not a heap based object, it can't be deleted "somewhere in the meantime". The image might be null, but that by itself wouldn't cause your application to crash unless you tried to iterate its pixels or something.
